What are the answers to the following geography questions, including calculations of distance using a map scale, and determining bus seating capacity?

The scale is $1 : 50000$, meaning $1 \text{ cm}$ on the map represents $50000 \text{ cm}$ in reality.
To convert centimeters to kilometers, we know that $1 \text{ km} = 1000 \text{ m} = 100000 \text{ cm}$.
So, $1 \text{ cm}$ on the map represents $\frac{50000}{100000} \text{ km} = 0.5 \text{ km}$.

Given the map distance is $8 \text{ cm}$.

The actual distance between Milner Estate and Stirling is $\boxed{\text{4 km}}$.

1.1.4 There is 1 national road clearly identifiable on the map (the N2).

1.1.5 East London is situated in the Eastern Cape Province.

1.1.6 Based on the map, Cambridge appears to be closer to the R102 road.

Question 2

2.1.1

There are 4 rows (A, B, C, D), and each row has 8 seats.

At the very back, there are two groups of 4 seats each.

The number of seats inside the bus, excluding the driver's seat, is $\boxed{\text{40 seats}}$.

2.1.2 Mr Dladla is in seat A5 (Row A, 5th seat from the front, on the right side of the aisle). His colleague is in D2 (Row D, 2nd seat from the front, on the left side of the aisle).

Here are the detailed directions:

1. From seat A5, Mr Dladla should move one seat to his left to enter the aisle.
2. Walk backward along the aisle, passing rows B and C.
3. Stop at row D.
4. Turn left into row D.
5. Walk past seat D1 to reach seat D2.
